Re: Where is Truth?
machine in a quasi-direct way. The second, the physical one, result from very deep long and competitive struggle between all universal machines. Would you restrict (your) machine to structural components within our inventory of today? Not at all. They can have many clothes, and many different type of relative clothes. HER functions to restricted into OUR present sortiment of activities? I like to call it an ORGANIZATION and no such restriction emerge. It is only a name. WE are orgqnizations as well, with unlimited (into our models that is) connections into the WORLD (infinite complexity of everything). Your Universal Computer may be even more compact and outreaching. (I am not talking about our present binary embryonic digital Kraxlwerks - we call our computers). *Assuming* yes doctor, you and me are such universal machine, but here you and me does not refer to our special earth-local incarnation, but all the arithmetical incarnations.

is endless! But there does seem to be a pattern to this madness! It seems as if for every kind of set there is a logic having its own algebra and isomorphic to some topological space.

Informally, the theorem states that arithmetical truth cannot be defined in arithmetic. Where then is it defined? You can defined arithmetical truth in second order arithmetic; or in set theory. I have often mentioned Tarski non definability of truth to explain that a machine cannot define its own knowledge notion, including in sane04 and almost all the papers of mine that I cite. We cannot define Kp by Bp True(p) because the machine cannot define, in its own language True(p). By the diagonalization lemma we would be able to construct Epimenides' paradoxical I am not true sentence. It might be possible to define knowledge (S4 modal operator) in some other way, but this has been shown impossible to by Kaplan Montague. Of course Gödel knew that Bp cannot be a knowledge operator. Amazingly it acts like a belief operator, confirming that the ideal science of the correct machine leads only to beliefs (roughly speaking). But we can define a knowledge operator at the metalevel, and this in the Theaetetus modus operandi, just by modeling the truth of an arithmetical proposition p by itself. This is the origin of the Bp p hypostase. It works fine and lead to the S4Grz logic. Also, I have often mentioned that, although a machine cannot compute nor even defined all its theology (the 8 hypostases), a rich Löbian machine, like ZF can define and study the whole theology of a simpler Löbian machine. Then, the rich LUM can lift that theology on itself, by betting on its own correctness, but at his own risk and peril: such an operation should not lead the machine to use its correctness as a brute fact (axiom), as this would make the machine unsound and inconsistant. I sometimes, when I want to be short, refer to a machine theology by describing it by the label Tarski minus Gödel, that is the truth on the machine minus what the machine can prove. Incompleteness means that it is quite different. Note that Löbian machines can still prove a Truth operator for each of all sentences with a bounded number of quantifier, and can approximate truth in many other ways, which I will not detail here. Tarski theorem is a fundamental component in the unravelling of the machine's theology. See my paper on Plotinus. The reason why the p hypostase, and the Bp p hypostase play the role of the ONE and the SOUL respectively, is that the introspecting machine can discover them despite not being able to give them a name, and so it matches the main defining attribute used for them by the neoplatonist inquirers.
